Doom

The AMD Ryzen 7 7700 paired with the AMD Radeon RX 7900 XTX delivers a formidable 1080p and 1440p experience in Doom, with the data showing a clear shift toward GPU limitation at 4K. This combination ranks in the 256th position out of 1681 tested configurations for this title, placing it comfortably in the top tier for high-refresh-rate gameplay.

Resolution Scaling

The measured frame rates reveal a predictable but steep decline as resolution increases, though the pattern indicates the system remains highly capable at every setting. At 1080p with Low settings, the combo produces an extraordinary 363.6 FPS average. Moving to 1440p at the same Low preset drops that figure to 232.5 FPS, a reduction of roughly 36%, while 4K Low lands at 124.8 FPS, which is about 46% lower than the 1440p result. This scaling curve is typical for a GPU-bound scenario at higher resolutions, but the absolute numbers show the RX 7900 XTX still has substantial headroom.

The gap between 1080p and 1440p is notably larger than the gap between 1440p and 4K for the Low preset, suggesting that at 1080p, the CPU begins to assert its influence on the frame rate ceiling. The Ryzen 7 7700’s 8 cores and 16 threads, with a boost clock up to 5.30 GHz, are sufficient to feed the GPU at lower resolutions, but the data indicates diminishing returns as pixel count rises. At 4K Ultra, the average FPS drops to 77.2, which is still playable but represents a significant 45% reduction from the 1440p Ultra score of 142.3 FPS.

The scaling from High to Ultra at each resolution is also informative. At 1080p, High yields 267.8 FPS while Ultra drops to 219.6 FPS, a 18% penalty for the highest preset. At 1440p, the same settings comparison shows 171.9 FPS versus 142.3 FPS, a 17% drop. At 4K, High produces 95.3 FPS while Ultra falls to 77.2 FPS, a 19% penalty. This consistent degradation across resolutions suggests that the Ultra preset imposes a similar relative load on the GPU, regardless of pixel count.

GPU Role

The Radeon RX 7900 XTX is the dominant component in this pairing, and its specifications align with the measured results. The GPU features 24 GB of GDDR6 memory on a 384-bit bus, delivering a bandwidth of 960.0 GB/s. This memory configuration is more than adequate for Doom, even at 4K with Ultra textures, and it likely explains why the frame rate drop from High to Ultra is not catastrophic. The card’s boost clock of 2498 MHz and game clock of 2365 MHz, based on the RDNA 3.0 architecture with 6144 shading units, provide the raw throughput necessary for the high average FPS observed.

The GPU’s pixel rate of 479.6 GPixel/s and texture rate of 959.2 GTexel/s are critical for a fast-paced FPS like Doom, where fill-rate demands scale quickly with resolution. The benchmark results place this GPU at the 85th percentile among all GPUs, with an average benchmark score of 44019. Its nearest rival, the AMD Radeon Pro 580, scores 44195, a delta of -0.4%, while the NVIDIA GeForce RTX 4070 Ti scores 44900, putting the RX 7900 XTX 2% behind. These comparisons suggest the card is well-positioned for high-end gaming, though not the absolute top performer.

At 4K Ultra, the GPU is clearly the limiting factor, as the average FPS of 77.2 is the lowest measured in the dataset. However, this is not a weakness of the card, but rather the expected result of pushing a demanding preset at the highest resolution. The 24 GB VRAM capacity ensures that memory is not a bottleneck, and the data supports this: the drop from High to Ultra at 4K is only 18 FPS, indicating that the extra VRAM usage does not cause a catastrophic frame rate collapse.

Settings Recommendations

For players targeting high refresh rates at 1080p, the data shows that even the Ultra preset is viable, with an average of 219.6 FPS. This is well above the threshold for 144 Hz displays, and the Low preset at 363.6 FPS is overkill for most monitors. The Medium preset at 317.4 FPS offers a balanced compromise, but the visual difference between Medium and Ultra is likely worth the 98 FPS trade-off if the display can handle it.

At 1440p, the Ultra preset delivers 142.3 FPS, which is still excellent for competitive play. The High preset at 171.9 FPS provides a slight edge for 165 Hz displays, and the data suggests that this is the sweet spot for most users. The Low preset at 232.5 FPS is unnecessary unless chasing maximum frame rates for esports-level responsiveness. The Medium preset at 203.2 FPS is a reasonable middle ground, but the jump to High adds only a modest performance cost.

At 4K, the situation changes. The Ultra preset drops to 77.2 FPS, which is playable but may not satisfy players with high-refresh 4K displays. The High preset at 95.3 FPS is a better choice, offering a 23% improvement over Ultra while maintaining visual fidelity. The Medium preset at 112.3 FPS is the recommended setting for a smooth 4K experience, as it stays above 100 FPS average. The Low preset at 124.8 FPS is viable for maximum performance, but the visual compromise is significant. For the best balance of visuals and frame rate, the Medium preset at 4K is the data-backed recommendation.

Q: Which resolution offers the best balance of performance and quality?

A: The 1440p High preset at 171.9 FPS average provides a strong balance, offering high visual fidelity without sacrificing frame rate.

Q: Is the CPU a bottleneck at 1080p?

A: The data suggests some CPU influence, as the frame rate scaling from 1080p to 1440p is larger than from 1440p to 4K, but the Ryzen 7 7700’s 8 cores and 16 threads still allow for very high frame rates.

CPU Role

The AMD Ryzen 7 7700 is a Zen 4 architecture processor with 8 cores and 16 threads, clocked at a base of 3.80 GHz and a boost of 5.30 GHz. Its benchmark results show strong single-thread performance, with a 3dmark single-thread score of 1049 and a Cinebench R23 single-core score of 4136. This is crucial for Doom, which relies heavily on single-core performance for game logic and draw calls. The CPU’s percentile ranking of 91 among all CPUs, with an average benchmark score of 40468, places it in the top decile.

In this game, the CPU’s role becomes more apparent at lower resolutions. The measured data shows that at 1080p Low, the average FPS is 363.6, which is likely near the practical ceiling for this processor in Doom. The nearest rival, the AMD Ryzen 9 7940H, scores 40431 with a delta of 0.1%, indicating that the 7700 is essentially on par with that mobile flagship. The Intel Core i9-13905H scores 40712, putting the 7700 0.6% behind, but this difference is negligible in real-world gaming.

The 32 MB of shared L3 cache is another factor that benefits Doom, as the game’s engine often accesses frequently used data. The dual-channel DDR5 memory support with a bandwidth of 83.2 GB/s ensures the CPU can feed the GPU without stalling. The data indicates that at 1440p and above, the CPU is less of a limiting factor, as the frame rate scaling aligns more closely with GPU load. At 4K Ultra, the average FPS of 77.2 is clearly GPU-bound, as the CPU has ample headroom to push higher frame rates if the GPU could keep up.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptionally high frame rates across all settings. The Low preset averages 363.6 FPS, Medium drops to 317.4 FPS, High yields 267.8 FPS, and Ultra produces 219.6 FPS. The spread between Low and Ultra is 144 FPS, showing that the GPU has significant overhead at this resolution.

At 2560x1440, the averages are 232.5 FPS for Low, 203.2 FPS for Medium, 171.9 FPS for High, and 142.3 FPS for Ultra. The gap between Low and Ultra narrows to 90 FPS, reflecting the increased GPU load. This resolution is the sweet spot for high-refresh-rate monitors, as even the Ultra preset maintains an average above 140 FPS.

At 3840x2160, the results are 124.8 FPS for Low, 112.3 FPS for Medium, 95.3 FPS for High, and 77.2 FPS for Ultra. The drop from Low to Ultra is 47.6 FPS, which is the smallest absolute difference across all resolutions, confirming that the GPU is the primary constraint. The 4K Medium setting at 112.3 FPS is notable because it remains above the 100 FPS mark, making it a practical choice for 4K gaming. The Ultra preset, while the most demanding, still provides a playable 77.2 FPS average, ensuring that players with 60 Hz 4K displays can enjoy the maximum visual quality without issues.
